Water heaters are good breeding grounds for bacteria. The anode and scale/sediment can harbor the bacteria and make any form of draining and filling ineffective.
Aluminum/zinc anodes are less likely to harbor the bacteria and thorough removal of the sediment will help. Much of the bacteria will be killed at temperatures over 160°F. Take whatever precausions are needed to prevent scalding. I installed a thermal mixing valve on mine to keep the water at the fixtures ~120 and keep the heating element temperature set nearly as high as it will go. More hot water is a nice added advantage.
